GIZ SEIP

• SEIP: “Sustainable Environment-friendly Industrial Production”

Implementation agreement from 16 June, 2016

• SEIP project is a part of the ongoing Indo-German Bilateral

Development Cooperation

• SEIP is a joint project of

- Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ)

- Ministry of Environment, Forest and Climate Change (MoEFCC)

• Focus on urban and industrial environmental management in India

• German contribution to the project is around EUR 5,000,000

(approx. 37 Crores INR)

• Implementation sites: Delhi, Haridwar and Vapi

• Objective: showcase solutions to reduce acute environmental

pollution and improve resource efficiency in industrial productionSlide 2

GIZ SEIP - Background

• Development in India is shaped by an advancing industrialization

• The Government of India has a vision to enhance the manufacturing

sector’s contribution to the gross domestic product to 25 per cent and

to create 100 million new jobs over the course of a decade.

• Currently, there are nearly 3,000 designated industrial zones in India,

some of which are very large, such as the industrial corridors,

investment regions, and manufacturing zones.

• The risks associated with industrial development include increasing

pollution levels, overuse of natural resources, and increasing amounts

of waste and wastewater, leading to endangerment of ecosystems.

GIZ SEIP – Project Activities

• Modernisation/upgradation of existing CETPs - Common Effluent

Treatment Plants

• Conveyance systems – industrial wastewater conveyance systems and

storm water drainage

• Online monitoring system - individual industries, CETP, River

• Skills development for operators (technicians, helpers) of industrial

wastewater treatment plant

• Environmental improvement in selected industries

• Awareness programms, clean-up drives

• Environmental Technology Platform

• Green rating and certification system for industrial areas

• New measures under policies/plans/programms

Actions …

• Suggest remarks for guidelines and directives for

online/continuous monitoring systems for industrial wastewater

• These documents will be implemented by the central and State

Pollutio Control Boards (environmental regulatory agencies)

Case Study II

Sludge dewatering at CETP Vapi, Gujarat (2016 / 2017)

• Sewage sludge moisture reduction and its management at

the industrial Common Effluent Treatment Plant in Vapi,

Gujarat

• Review of information and identification of key issues

• Field visits and problem analysis

• Preparation of pre-feasibility report

Case Study II

Main waste water and sludge operation parameters

• Waste water inflow around 55,000 m3/d

• High loaded stream of 120 m3/d feed to UASB-Reactor(COD > 20,000 mg/l)

• Sludge production around 70,000 t sludge per year(with a Dry Solids Concentration of around 23 % DS and

a volatile fraction of 52 %)

Slide 12Case study II

Case Study II

Recommendations

• Optimization/ New installation

of an anaerobic sludge treatment(higher biogas production,

less remaining sludge)

• Sludge drying (e.g. solar drying)(test shows DS > 90 % after 40 days for solar drying)

• Energetic use of the dried sludge to replace the sludge

drying beds(reduction of space demand, smell, further emissions)

• Further options: Thermal hydrolysis Slide 13

Slusge drying beds

• Large space demand, relevant emissions

• Limited drying effectivity because of the sludge crust

(layers below are not drying well)

Solar drying

• Applied for municipal sludge

and industrial sludge

(e.g. textile factory in India)

• Surface of the sludge

is broken off permanently

• Dry Solids Concentration > 90 %

• Dried sludge usable as energy

source (e.g. Cement Factories)

Dried sludge, hygienized,

DS > 90 %

Conclusion

• GIZ SEIP projects supports a sustainable development

in the industrial sector in India

• Online Monitoring as useful tool for operation and

supervision

• Sludge treatment as one main open task

in many industrial parks

• Sludge as energy source (biogas, as substitute fuel)

• Thanks to all project partners for the intensive

technical exchange and discussions
